PURPOSE:To obtain a car antenna device which is convenient for washing of the car, etc., by making an antenna main body removable from the antenna base part. CONSTITUTION:A car antenna device consists of an antenna main body part and an antenna base part. The antenna main body part contains antenna elements 3-5 protruding to the outside and a printed base board 9 having an electric circuit to ensure the impedance matching. The elements 3-5 are connected electrically to the board 9, and the output signals of these antenna elements are transmitted to a conductive contact 22. The antenna base part is provided on an attachment tool 6 which is used to attach the antenna to a car and contains a terminal 23 which receives the signal from the contact 22 and a cable 8 connected to the terminal 23. The antenna main body part can be freely attached to and detached from the antenna base part. |
